This removes the `attr` matcher and adds a `meta` matcher. The previous `attr`
matcher is now ambiguous because it doesn't disambiguate whether it means inner
attribute or outer attribute.
The new behavior can still be achieved by taking an argument of the form
`#[$foo:meta]` (the brackets are part of the macro pattern).

Some unix platforms will send a SIGPIPE signal instead of returning EPIPE from a
syscall by default. The native runtime doesn't install a SIGPIPE handler,
causing the program to die immediately in this case. This brings the behavior in
line with libgreen by ignoring SIGPIPE and propagating EPIPE upwards to the
application in the form of an IoError.

It turns out that on linux, and possibly other platforms, child processes will
continue to accept signals until they have been *reaped*. This means that once
the child has exited, it will succeed to receive signals until waitpid() has
been invoked on it.
This is unfortunate behavior, and differs from what is seen on OSX and windows.
This commit changes the behavior of Process::signal() to be the same across
platforms, and updates the documentation of Process::kill() to note that when
signaling a foreign process it may accept signals until reaped.
Implementation-wise, this invokes waitpid() with WNOHANG before each signal to
the child to ensure that if the child has exited that we will reap it. Other
possibilities include installing a SIGCHLD signal handler, but at this time I
believe that that's too complicated.

So far, we've used the term POD "Plain Old Data" to refer to types that
can be safely copied. However, this term is not consistent with the
other built-in bounds that use verbs instead. This patch renames the `Pod`
kind into `Copy`.

HashMap and HashSet require keys to implement TotalEq. This makes it possible to use TypeId as a HashMap key again.
Question for reviewers: assuming we want to support `HashMap<TypeId, whatever>`, would it make sense to add a relevant test? If so, should it go to libcollections or libstd?

This reverts commit 7180b5de44.
We don't particularly need this, I've never seen it clutter up the docs, it just seemed nice at the time. Sadly it caused a regression for reexported methods.
Closes#13091
The previous dependency calculation was based on an arbitrary set of asterisks
at an arbitrary depth, but using the recursive version should be much more
robust in figuring out what's dependent.
A variety of stuff here, mostly aimed at making `make install` work correctly with `--libdir` and `--mandir`. `make install` again goes through `install.sh`.
This commit removes implicitly adding the Send bound to ~Trait objects and
procedure types. It will now be manually required to specify that a procedure
or trait must be send-able.
Closes#10296
This bench is meant to exercise libgreen, not libnative. It recently caused the
auto-linux-32-nopt-t bot to fail as no output was produced for an hour.
We really do *not* want TCO to kick in. If it does, we'll never blow the
stack, and never trigger the condition the test is checking for. To that end,
do a meaningless alloc that serves only to get a destructor to run. The
addition of nocapture/noalias seems to have let LLVM do more TCO, which
hurt this testcase.
When calling
make verify-grammar
a lot of errors are reported by llnextgen.
Only simple errors like:
missing semicolons,
missing single quotes,
usage of parentheses instead of squared brackets or
usage of single quote instead of double quote
are fixed by this patch.
This can only be tested, when llnextgen is installed.

or when llnextgen is not installed:

This patch adds the keyword "crate" to the grammar in rust.md.

The `_match.rs` takes advantage of passes prior to `trans` and
aggressively prunes the sub-match tree based on exact equality. When it
comes to literal or range, the strategy may lead to wrong result if
there's guard function or multiple patterns inside tuple.
Closes#12582.
